Although a possibility it is unlikely the date is wrong.The only other time I have had cause to use the Arboretum site it proved correct.Strangely that was to track down the date of the death of my uncle's best friend who died in a Meteor T7 as an instructor in 1955 at Gamston,then a satellite for Worksop.He fell victim to a botched assymetric overshoot(simulated engine failure)by his student.
The bare bones of Driffield are still there as I frequently fly over it in my Cessna 150 but diminish year by year.Used to be part of The Defence School of Transport based at Leconfield down the road but that may have changed.
Yes I too feel a bit like an "honorary" scouser not having been "home" in over 30yrs!!
